Covalent organic frameworks COF-1 and COF-5 crystals with excellent textural properties were obtained for the first time in a 0.5 L synthesis vessel within 1–2 h by sonochemical route.
Abstract We developed and designed a bifacial four-terminal perovskite (PVK)/crystalline silicon (c-Si) heterojunction (HJ) tandem solar cell configuration albedo reflection in which the c-Si HJ bottom sub-cell absorbs spectrum from both front rear sides (reflected light background such as green grass, white sand, red brick, roofing shingle, snow, etc.). Using subsequent short-circuit current density, conversion efficiency of PVK-filtered was improved regardless PVK top properties. This...
Abstract Invisible power generation by natural and artificial light enables sustainability onsite‐power deployment, lower cost, minimal burden on the built environment. However, dark, opaque photovoltaics limit utilization in a transparent way. Herein, it is proposed that active energy window (AEW) invisibly features production, providing higher freedom for onsite generators objects without limiting human vision. The AEW has photovoltaic (TPV) heater (TH) to remove effects of shadows from...
Abstract The rapid growth in the transparent electronics industry has increased need for photovoltaic cells (TPCs) and self‐powered devices. To make TPCs devices more efficient, a detailed understanding of device structure is needed. In this study, TiO 2 /NiO heterojunction‐based were fabricated with different layer thicknesses, effect thickness on photovoltage photocurrent was evaluated. All had high optical transparency (>50%) visible–near‐infrared (vis–NIR) region. illuminated power...
We present the self-healing of defects and enhanced crystallinity in uniaxially aligned poly(3-hexylthiophene) (P3HT) crystal via molecular doping with F4TCNQ. Using eutectic friction transfer (EFT), highly P3HT films (P3HT EFT )...
An adjoint-based Navier‐Stokes design and optimization method for two-dimensional multi-element high-lift configurations is derived presented. The compressible Reynolds-averaged equations are used as a flow model together with the Spalart‐Allmaras turbulence to account high Reynolds number effects. When viscous continuous adjoint formulation used, necessary aerodynamic gradient information obtained large computational savings over traditional finite difference methods. configuration parallel...
☞Introduction and Motivation➣While aerodynamic prediction methods based on CFD are now well established,accurate, robust, the ultimate need in design process is to find theoptimum shape which maximizes performance.➣During last decade optimization oncontrol theory have been perfected for rigid wings with fixed planforms.➣Example: Redesign of wing a Boeing 747 fuselage.
Contraflow, or lane reversal, is a way of increasing outbound capacity real network by reversing the direction inbound roads during evacuations. The contraflow considered potential remedy to solve congestions evacuations in context homeland security and natural disasters (e.g., hurricanes). Currently available algorithms only tackle single-source multiple-destinations situation. These approaches cannot handle multiple-sources problem which harder due conflicts across optimal paths from...
Forming heterostructures based on hybrid photocatalysts has been considered as one of the most effective techniques for improving photocatalytic efficacy semiconductor photocatalysts. To address this issue, article describes ZnO/TiO₂ heterojunction thin films that were produced via direct current reaction magnetron sputtering technique and with varying thickness TiO₂ coating.

Solar-driven hydrogen generation is one of the most promising approaches for building a sustainable energy system. Photovoltaic-assisted photoanodes can help to reduce overpotential water splitting in photoelectrochemical (PEC) cells. Transparent improve light-conversion efficiency by absorbing high-energy photons while transmitting lower photocathode production. In this work, transparent were implemented forming metal–oxide junctions NiO/TiO2 heterostructures creating photovoltaic effect....

The effects of chromatic dispersion (CD), polarization-mode (PMD), and polarization-dependent loss (PDL) on the intensity noise suppression spectrum-sliced incoherent light sources achieved by using gain-saturated (GS) semiconductor optical amplifiers (SOAs) are investigated. Passing through SOAs, excess (EIN) originating from beating spontaneous emission against itself can be greatly reduced. However, since is an elaborate balancing between numerous frequency/polarization components light,...
